WebJul 1, 2010 · The wealth of experimental observations on mammalian hearing implies that few experimentally accessible tests of the critical-oscillation hypothesis remain to be performed. Put another way, the strength of the hypothesis lies less in its predictive ability than in its capacity to accommodate a broad range of existing observations in a unified ... WebApril 22, 2009: Utah and Texas researchers have learned how quiet sounds are magnified by bundles of tiny, hair-like tubes atop “hair cells” in the ear: when the tubes dance back and forth, they act as “flexoelectric motors” that amplify sound mechanically. “We are reporting discovery of a new nanoscale motor in the ear,” says Richard Rabbitt, the study’s …

Flexoelectricity refers to the mechanical-electro coupling between strain gradient and electric polarization, and conversely, the electro-mechanical coupling between electric field gradient and mechanical stress. This unique effect shows a promising size effect which is usually large as the material dimension is shrunk down. Moreover ...
